Finding an official "portable" version of GOM Inspect 2018 (now known as ZEISS INSPECT) is difficult because the software is traditionally provided as a full installer requiring roughly 3.7 GB of disk space.

If you need a player that updates automatically or prefer open‑source software, VLC or MPC‑HC are excellent fallback choices.

If You Absolutely Need Portable 3D Inspection (Free)

Consider CloudCompare – it’s open-source, portable versions exist on PortableApps.com (unofficial), and it supports distance computation, mesh comparison, and sectioning. Not identical to GOM, but capable for many tasks.

  1. Visit the official GOM (now part of ZEISS) website to find GOM Inspect editions and system requirements.
  2. Download the free edition or request a trial of the full package from the vendor.
  3. If you need a portable workflow, consider running the software on a dedicated portable Windows environment (e.g., a properly licensed Windows To Go USB) rather than using an unofficial portable executable.
  4. Verify downloads with publisher-provided checksums and scan with updated antivirus.

NVIDIA Quadro or GeForce with at least 2GB VRAM (OpenGL 3.3+ support is critical). 8GB minimum (16GB+ recommended for large meshes).
